Mac <-> DC Programmer Thread

oookay! I just edited environ.sh and 'Hello World VMU' and 'Made on a Mac' compiled without errors via Xcode. The only point I see is that Xcode (I dunno about ProjectBuilder on Jaguar) puts the results in a folder named 'build', wich is more tidy... let's see if I can find on the doc how to do this.

Good work nobody_

Well, for those with Panther, I've located the Xcode project template folder:

Code: Select all

/Library/Application Support/Apple/Developer Tools/Project Templates

cheers

Oh, another thing I just ran accross... I forgot to take a bitmap out of the Dual-Platform SDL Romdisk template folder before I distributed it. I'll put up a new archive, but for those of you who already have it, empty the SDL template's Romdisk folder so your programs won't get unnecessarily large

And thanks, hikikomori, I was a little worried it wouldn't work in Xcode.

what is a .sitx file exactly?

nobody in particular · Fri Jan 16, 2004 8:19 pm

It's a newer version of the Stuffit .sit file. You can open it with recent versions of Stuffit Expander.

anyone tried to get sh-elf-gcc to do objective C yet? I've somehow gotten sh-elf-gcc and sh-elf-g++ and stuff built, but I haven't gotten as far as being able to test them, yet.
(ahh, using gcc-3.3.2, binutils 2.14, and newlib 1.9.0)

I've also been trying to compile kos-1.2.0...

Though, the jpeglib && pnglib .h files (whatever they're called, I can't remember) are somewhere in the kos/addons/ directory... Seems when the Makefile's trying to make vqenc it doesn't use the KOS_ALL_INCS variable from Makefile.rules. Got me as to why, or why when I tried "fixing" that it didn't do a damned thing.

*** seems I somehow missed the last page of posts - the one containing information about a patch. I'm gonna try that now. ***

gwahh!

I /know/ I have zlib. Somewhere.

I've been writing Dreamcast programs in Objective-C (best language ever

). I've got a KOS version of libobjc avaliable at the same site as the previously mentioned Project Builder template.

In response to the zlib issue: add -lz to the linker flags in vqenc's Makefile.

greay · Post by **greay** » Fri Jan 23, 2004 1:57 am

cool, I'm gonna try that out, after I get this whole arm_elf thing worked out (seems the build failed last time I tried; not sure why). the kallistios build failed b/c I was reusing my old environ-dc script; I forgot to add KOS_MAC="true" in there. But then I get an error about the arm-elf thing. :/

Grr... seems some more work's ahead for me.

greay · Post by **greay** » Fri Jan 23, 2004 6:19 am

Okay. One would think that everything should work now. Got the compilers built and installed; got kallistios built, and am trying out the examples.

Now, the makefiles there do funny things, but I managed to compile one of the examples (2ndmix) by hand.

what happens is this: I want to test it, and don't have a cable yet, so I'm going to make a CD: first step is run "sh-elf-objcopy -O binary 2ndmix.elf 2ndmix.bin", right? I get this message:

sh-elf-objcopy: 2ndmix.bin: File truncated

and the file size of 2ndmix.bin is 0. any idea where I went wrong?

Someone on the KOS mailing list had a similar problem, maybe this could help: http://sourceforge.net/mailarchive/mess ... id=6870495

greay · Post by **greay** » Fri Jan 23, 2004 9:22 pm

cool. Ugh. I ended up getting around the problem by moving backwards in version - I'm using the precompiled toolchains posted earlier on in this forum, now. Maybe I can switch back, now, so all that hard work (using the most recent versions of all the tools) won't be for naught.

That's for another time, though... I don't want to have to go through all that again.

I'm in the midst of porting libFoundation to the dreamcast/KOS. It's causing me hell, but I'm sparing no expense in mangling things, and I've gotten this far: it does build; that is, I have libFoundation.a

Unfortunately, it does this producing a /whole lot/ of warnings; I've gotten rid of most of them, but now I'm going through all the "implicit declaration of function `foo'"s...

As a sample of these implicitly declared functions, there's open, fstat, read, close, chmod, utime... A whole bunch of others. I've been looking at the KOS documentation, and it seems a lot of these fns have equivalents (although I can't seem to find one for fstat).

Hmm, what else... Ahh, yes. Though fairly sure it wdn't work, I made a quick "Hello, world" program to test the library (using NSObject)... It failed miserably during linking - the first of the errors was

libFoundation/NSObject.m:260: undefined reference to `___objc_class_name_ObjcRuntimeException'

Now, the code segment for this is:

+ (oneway void)release
{
}

... I'm a bit lost as to where the reference is.
So, my question is, anyone interested in help out in this endeavor? I don't really have anywhere to host the stuff, but the .tar.gz file's only 280K.

nobody in particular · Tue Feb 03, 2004 2:27 pm

Send it to me, I'll take a look at it.

greay · Post by **greay** » Wed Feb 04, 2004 9:29 pm

gahh.. My SMTP server's not working right now.

gotta run to work now, but I managed to get quite a bit done yesterday/today: I've narrowed the problems (i.e., errors while linking) to a couple fns:

select()
vfprintf() // haven't looked at it, printf() might work?
lseek() // kos seems to have an equivalent, but I haven't found it
ftruncate() // same, maybe just comment it out?
dlopen()
dlerror()

hey, anybody here had any luck using the coder's cable? I finally got my USB->Serial adapter, and I'm running into trouble compiling dc-tool.

(i.e., syscalls.c: In function `dc_dreaddir': .. error: structure has no member named `d_off')

EDIT:... Why does the "search" never work for me? I had to find the post on this board through google. grr.... anyway, it seems someone has, but the page is down. I'll keep looking.

Where you able to get kos working using the jpeg and png libraries included with it? And did you use matts patch?

What brand & model usb<-> serial adapter are you using?

if syscalls.c is in the dc's 'side' then i bet something before it didnt get defined in a previous header file.

dc_dreaddir.d_off = dc d ? read directory
the member "d_off" is just probably an int ( 1-on,0-off).
